Causes Of Disease

  • Brain protein fails to function normally and disrupts the work of brain cells (neurons). It triggers a series of toxic events. Hence neurons get damaged and they lose their connection to each other and they eventually die.
  • Alzheimer’s disease is caused by a combination of genetic, lifestyle and environmental factors that affect the brain over time.
  • It is caused by specific genetic changes that virtually guarantee a person will develop the disease.
  • In a person with Alzheimer’s the brain tissue has fewer and fewer nerve cells and connections and tiny deposits, known as plaques and tangles, build upon the nerve tissue.
  • Plaque develops between the dying brain cells. They are made from a protein known as beta-amyloid. The tangles meanwhile occur within the nerve cells. They are made from another protein tau.


There is no known cure for Alzheimer’s disease, It is not possible to reverse the death of brain cells. Family and social support play a key role.
